CHURN.

SPECIFICATION forming part of Letters Patent No. 659,087, dated October 2, 1900.

Application filed July 28, 1900.

T0 at whom, it may concern.-

*Be it known that I, JOSEPH H. MCOAUS- LAND, a citizen .of the United States, residing at Lampasas, in the county of Lampasas and State of Texas, have invented new and useful Improvements in Ohurns, of which the following is a specification.

The object of my invention is to provide a simple, cheaply-constructed, and easily-operated churn by means of whicha thorough and complete but gentle agitation of the cream contained therein may be effected, so that the butter-cells in the cream will not be ruptured or broken and a superior quality of butter thereby obtained.

In carrying out my invention I employ a cylindrical body having a depression in the bottom thereof, constituting one bearing for the dasher-shaft,a cap adapted to be screwed upon the top of said body and having a depression therein for receiving the other end of the dasher-shaft, a series of spirally arranged dasher-blades on said dasher-shaft, and suspending means for said body whereby a reciprocatory back-and-forth movement may be imparted thereto.

The details of the invention will be more fully set forth hereinafter, and the novel features of the invention will be defined in the claim.

In the drawings forming part of this specification, Figure 1 is a perspective view of my improved churn in operative position. Fig. 2 is a longitudinal section of the same, and Fig. 3 is a cross-section.

Like reference-nu merals indicate like parts in the diiferent views.

The body 1 of my improved churn is cylindrical in form and provided with a depression 2 in the bottom thereof, constituting a bearing, as will hereinafter appear. Secured to opposite sides of the body 1 are loops 3 3, through which straps 4 and 5, surrounding said body, are passed. Said straps 4 and 5 are connected by a strap 6., having a ring or eye 7 at its central point for attachment to a hook, nail, or other like support. Said strap is shown as made intwo parts, one of said parts being provided with a snap-hook Sand the other with a loop or eye 9, adapted to be engaged by said hook. The parts of the strap 6 are permanently secured to the straps 4 and 2 Serial No. 25,159. (No model.)

5, respectively, and the snap-hook 8 and eye 1 on opposite sides thereof are handles 10, as

clearly shown.

' The upper end of the body 1 is formed with external screw-threads 11, with which are adapted to engage internal screw-threads 12 upon a closing-cap 13. In order to provide a tight joint between these parts, a rubber ring or gasket may be employed. The cap 13 is provided with a tapering recess or depression 15 at its central portion and is also provided with means whereby a wrench may .be applied to it for the purpose of screwing the same upon the body 1 and unscrewing the same therefrom.

Within the body 1 is located a dasher, comprising a central longitudinally-extending dasher rod or shaft 16, having a series of spirally-arranged blades 17 secured thereto and located at regular: intervals apart. One end of the shaft 16 fits within the recess 2 in the bottom of the body 1, and the other end fits within the recess or depression 15 in the cap 13. By reason of the tapering form of the recess or depression 15 the shaft 16 will be properly centered when the cap 13 is in place by the engagement of the end of said shaft with the inner surfaceof said recess. When the cap 13 is screwed down upon the body 1, so as to seal the same, the bottom wallof the recess 15 in the cap 13 is brought into close contact with the end of the shaft 16, and the dasher is thereby locked in place against longitudinal or rotary movement independent of the body 1.

In using the device the body 1 is placedin an upright position and filled to the proper extent with cream. The dasher is then inserted and the cap 13 applied, the same being screwed down, so as to prevent any leakage of-cream from the interior of the churn. The body 1 is then turned to a horizontal position and suspended by the ring 7 from a hook, nail, or other analogous device. A reciprocating or oscillating movement is then given to the churn by simply pushing on one end thereof. The power required for this is very small and, in fact, a heavy churn can be operated by a child. During this oscillatory movement of the body 1 the cream is caused to flow back and lOO forth from one end of the churn to the other, coming in contact with the spiral blades 17 of the dasher and having a gyratory movement imparted thereto. As the movement of the churn itself is gentle, the action of the cream against the dasher will be likewise gentle, and danger of breaking up the buttercells in the cream is thereby prevented. At the same time a thorough and complete agitation of the cream is obtained, with the result that the butter obtained is in agranular condition, with a pleasant nutty flavor.

I have heretofore stated that the dasherrod 16 is locked in position by the engagement of the cap 13 with one end thereof. It may be desirable, however, to provide for the rotation of said dasher-shaft through the action 'of the cream on the spirally-arranged blades 17, secured thereto. In this event the cap 13 will not be screwed up so far on the body 1 as to cause a locking engagement with said shaft. The recesses or depressions 2 and 15 therefore would serve as bearings for the shaft.

I have shown and described but one embodiment of my invention, the same being that which is deemed by me at this time to be the preferable one. It is obvious, however, that many minor changes in the construction and relative arrangement of parts may be made without departing from the nature or spirit of my invention, and I do not desire to be limited to the exact details shown, except as defined by the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A churn comprising a cylindrical body having a recess in the bottom thereof, and screwthreads upon the upper open end thereof, suspending means for said body which provides for the support of the same in a horizontal position and for an oscillatory movement to be imparted thereto, a cap screwed upon the upper end of said body having a central tapering recess or depression therein, and a dasher located within said body and comprising a central longitudinal shaft and a series of spirally-arranged blades thereon, the broad faces of said blades lying at an angle to the direction of oscillation of said body,

-the opposite ends of said shaft fitting Within JOSEPH H. MCOAUSLAND.
